Is the MP race over ??

With the release of the A7s and it's 12MP sensor, one could think that the MP race is over ? The release of the A77 II is just around the corner, so if that camera has as rumoured 32MP on a APS-C sensor, is that not overkill ? now that Sony seems to turn to less MP, I don't see here or in the E-mount discussions any complaines about insufficient MP for the A7s, so why is it needed to have 32MP on a APS-C sensor for the A77 II if rumours are true ????would it not be better for Sony to stick with 24MP for the A77 II, what do you think about this back to the past at 12MP ?? and why not less MP for a APS-C sensor. thanks.
